Limestone on acidity?

I have three questions.





1. What is the formula for magnesium carbonate and calcium carbonate?





What if the form of calcium in this compound? Is it calcium ion or calcium metal?





2. Can someone show me the chemical equation for limestone correcting the pH of acid soils?





3. Why is it that plants like azaleas, camellias, and rhododendrons should not be given limestone?

Limestone on acidity?
1. Others have already given you the formulas. Any time calcium is in a compound, as opposed to being 'on its own' it will be the calcium ion with a charge of 2+.


2. Limestone is CaCO3. The carbonate ion, CO3^2-, is basic. It accepts hydrogen ions (acid, H+) to form CO2 and H2O. This neutralizes and even renders basic the soil. CaCO3 + H+ --%26gt; H2O + CO2 + Ca^2+


3. Those plants grow best in acidic soil. So don't give them limestone because it will make the soil basic.
Reply:CaCO3 is calcium carbonate.
Reply:i have 3 answers 1.CaCO3 = cal carb mag carb=MAMO2.PUT 18 PERCENT TYPE N HYDRATED LIME IN THE SOIL .ROTOTILL.CHECK FOR PERFECT BALANCE IN 2 WEEKS.ADJUST AS NEEDED 3.THESE PARTICULAR PLANTS ARE NOT IN NEED OF LIMESTONE AS THEY PRODUCE ENOUGH FERTILIZER ON THIER OWN.BEST WISHES FREDDY.......
Reply:magnesium carbonate is MgCO3 while calcium carbonate is CaCO3.
